45.A.hear B.think C.look D.tell(A)The World’s Water Shortage The world is not only hungry.but it is also thirsty for water.This may seem strange to you. since nearly 70 percent of the earth’s surface is covered with water.But about 97 percent of this huge amount is sea water.or salt water.Man can only drink and use the other 3 percent--the flesh water from rivers.lakes.underground.and other sources.And we cannot even use all of that.because some of it is in the form of icebergsand glaciers.Even worse.some of it has been polluted. However.as things stand today.this small amount of fresh water is still enough for us.But our need for water is increasing rapidly--almost day by day.Only if we take steps to deal with this problem now can we avoid a serious worldwide water shortage later on. We all have to learn how to stop wasting our valuable water.One of the first steps is to develop ways of reusing it. Today in most large cities.water is used only once and then sent out into a sewer system.From there it returns to the sea or runs into underground storage tanks.But it is possible to pipe used water to a purifying plant.There it can be treated with chemicals so that it can be used again.just as if it were fresh from a spring. But even if every large city purified and reused its water.we still would not have enough.All we’d have to do to make use of the vast reserves of sea water in the world is to removethe salt. If we take these steps we’ll be in no danger of drying up. 查看更多

When you read an article you will understand and remember it better if you can work out how the writer has put the ideas together.Sometimes a writer puts ideas together by asking questions and then answering them.For example,if the article is about groundhogs(土撥鼠),the set of questions in the writer’s head might be:
What does a groundhog look like?
Where do groundhogs live?
What do they eat?…
In the article,the author might answer those questions.
Sometimes an author writes out her questions in the article.These questions give you signals.They tell you what the author is going to write next.Often an author has a question in her head but she doesn’t write it out for you.You have to work out her question for yourself.Here’s a sample reading for you to practice this method.
Earthworms
Do you know how many kinds of earthworms there are?There are about 1800 kinds in the world! They can be brown,purple,green.They can be as small as 3 cm long and as large as 3 m long.
The best time to see earthworms is at night,especially a cool,damp night.That’s when they come up from their burrows(地洞)to hunt for food.Earthworms don’t like to be in the sun.That’s because they breathe through their skin,and they can’t breathe if their skin gets too dry.Earthworms must come out of the earth if it rains a lot,because they can't breathe in their flooded burrows.What a dangerous life!
Earthworms don't have eyes,so how can they tell when it's dark? They have special places on their skin that are sensitive to light.These spots tell whether it’s light or dark.If you shine a flashlight on an earthworm at night,it will quickly disappear into the ground.
Earthworms don't have ears either,but they can hear by feeling movements in the earth.If you want to hear like an earthworm,lie on the ground with your fingers in your ears.Then have a friend stamp his or her feet near you.This is how earthworms feel birds and people walking,and moles digging,near them.
Earthworms are useful.Farmers and gardeners like having lots of earthworms in their land because the worms help to make better soil when they dig.That digging keeps the soil loose and airy(通風的).In one year earthworms can pile up as much as 23,000 kg of castings in an area about the size of a football field.
【小題1】What’s the purpose of reading Earthworms?

A.To show the special life facts of earthworms.
B.To explain the differences from the groundhogs.
C.To put the writer’s idea into real use.
D.To make the readers think more clearly.
【小題2】Which question CANNOT be answered in the passage?
A.How do earthworms help with gardeners?
B.What life are earthworms living with?
C.When may people observe earthworms?
D.Why can human listen like earthworms?
【小題3】How can you understand Earthworms better according to this passage?
A.Read, ask and answer questions in your own head while reading.
B.Read to work out all the questions in the writer’s head while reading.
C.Read and check all the things that are not clear to you again and again.
D.Read for general ideas and discuss or compare with other similar topics.
【小題4】What’s the best title for the passage?
A.One way to help with understanding
B.One way to practice with a new idea
C.One way to learn to be a wise writer
D.One way to be clearer about worms
